To a solution of 6-bromo-3H-imidazo[4,5-b]pyridine (1.0 g) in THF (20 mL) at 0° C. was added sodium hydride (187 mg) and the reaction stirred at 0° C. for 1 h. Then, 2-(trimethylsilyl)ethoxymethyl chloride (0.94 mL) was added and the reaction stirred at room temperature for 16 h. The reaction was quenched with water (20 mL) and extracted into ethyl acetate (2×20 mL). The combined organics were washed with aqueous brine solution (2×20 mL), dried (MgSO4), reduced in vacuo and purified by column chromatography to give 6-bromo-3-(2-trimethylsilanyl-ethoxymethyl)-3H-imidazo[4,5-b]pyridine.
